Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of support pad positioning, in particular to an electric bed and a support pad positioning structure. BACKGROUND

[0002] An electric bed is a device that can control at least a part of a bed frame to be lifted by an electric mode, so that the height of the head, foot or other parts of the bed plate changes, thereby realizing the change of the bending degree of the bed plate. The electric bed can be widely applied in different scenes such as daily life and hospital care to meet the use requirements of users and improve the use comfort.

[0003] During the lifting of the bed frame, the mattress may slip, therefore, the existing electric bed often sets a support protruding from the bed surface at the foot position to prevent the mattress from slipping backward. However, this foot support makes the user feel uncomfortable when getting on and off the bed, and even if this support is set, when the mattress exceeds the height of the support, the mattress is still easy to come off.

[0004] At the same time, when the bed frame is lifted, the support at the foot position cannot guarantee the fit between the mattress and the bed frame, and the middle part of the mattress is easy to arch. Moreover, in the lifted state, the mattress has a downward sliding trend, which will generate a strong extrusion on the support at the foot position, thereby causing the deformation of the mattress and affecting the service life of the mattress.

[0084] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. In addition, it should be understood that the specific implementation described herein is only used to illustrate and explain the present application, and is not used to limit the present application. In the present application, the orientation words such as "upper", "lower", "left", "right" generally refer to the upper, lower, left and right in the actual use or working state of the device, and specifically refer to the picture direction in the drawings.

[0085] In addition, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.

[0086] The present application provides an electric bed and a support pad positioning structure, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0087] The embodiments of the present application provide an electric bed, please refer to Figure 1 which includes a bed frame 100 and a mattress 200. Exemplarily, the bed frame 100 has a first side 150 and a second side 160 opposite to each other. Generally, the first side 150 is the upper side and the second side 160 is the lower side. The mattress 200 is arranged on the first side 150 of the bed frame 100, that is, the mattress 200 is arranged on the bed frame 100.

[0088] Among them, please refer to Figure 2 The bed frame 100 can be arranged on a bottom support 300, which can include a bed leg and the like, which is well known to those skilled in the art. It can be understood that the bottom support 300 in the drawings of the present application is only an example, which does not constitute undue limitation on the present application.

[0089] The electric bed further comprises a driving member (not shown in the figure), which can be a driving motor, an electric cylinder, a pneumatic cylinder, etc. The driving member is connected to the bed frame 100 and can drive at least a part of the bed frame 100 to be lifted. The specific arrangement position and number of the driving member can be arranged according to actual needs. The electric bed basically comprises a motor or other driving member for driving the bed frame to be lifted, which is well known to those skilled in the art and can be designed according to actual needs. The driving member in the present embodiment is not improved, so it will not be described in detail.

[0090] For example, please continue to refer to Figure 2 The bed frame 100 comprises a first bed frame 110, a second bed frame 120, a third bed frame 130 and a fourth bed frame 140 connected in sequence. When a user lies on the electric bed, the first bed frame 110 corresponds to the head and back position of the user, the second bed frame 120 corresponds to the hip position of the user and can also be referred to as a hip bed frame, the third bed frame 130 corresponds to the thigh position of the user, and the fourth bed frame 140 corresponds to the lower leg and foot position of the user. Two driving members are respectively connected to the first bed frame 110 and the third bed frame 130, and the first bed frame 110 and the third bed frame 130 can be lifted by the driving of the driving members, so as to adjust the posture of the bed frame 100. Here, since the fourth bed frame 140 is connected to the third bed frame 130, the fourth bed frame 140 is also driven by the third bed frame; or a driving member can be further arranged to lift the fourth bed frame 140, etc. It can be understood that the arrangement of the bed frame 100 and the driving member is not limited to the above, and the bed frame 100 can also have other forms, such as only having a first bed frame 110, a second bed frame 120 and a third bed frame 130, or more or fewer parts, etc. The driving member can also be connected to the bed frame 100 in different ways, such as only arranging one driving member connected to any part of the bed frame 100 and capable of driving the part to be lifted. This is achievable for those skilled in the art, and the examples in the present embodiment do not constitute an improper limitation on the present application.

[0091] For example, Figure 2 That is, a state of the mattress 200 after being lifted is shown. It can be understood that this is only an example and does not constitute an improper limitation on the present application. In some embodiments, after the bed frame 100 is lifted, the bed frame 100 and the mattress 200 can also be in other inclined states.

[0092] Here, when the bed frame 100 is lifted, the mattress 200 on the bed frame 100 will be lifted synchronously, and then the mattress 200 will be lifted to an inclined state. Due to the action of gravity, the mattress 200 will slide downward and change the relative position between the mattress 200 and the bed frame 100, thereby causing a part of the mattress 200 to be raised or the mattress 200 to be out of the bed frame 100, etc.

[0093] To this end, in the embodiments of the present application, please refer to Figure 3 At least one passage 170 is provided on the bed frame 100, exemplarily, two passages 170 are provided on the second bed frame 100 and the fourth bed frame 100 respectively. Exemplarily, the passages 170 on the bed frame 100 can be provided in groups, each group of passages includes two passages 170 which are symmetrical in the width direction of the bed frame, i.e. each group of passages includes two passages 170 which are axially symmetrical along the center line of the bed frame 100 in the length direction. Of course, it can be understood that in other embodiments, the positions and the number of the passages 170 are not limited to the above, for example, one, two, three, five, six or other number of passages 170 can be provided, and the examples in the embodiments do not constitute undue limitation.

[0094] Please refer to Figure 4 Here, the passage 170 penetrates the first side 150 and the second side 160 of the bed frame 100. Please further refer to Figures 5-7 and pay attention to Figure 6 and Figure 7 A fastener 400 is further provided on the second side 160 of the bed frame 100, and a connecting piece 500 is provided on the mattress 200, the connecting piece 500 is provided with a matching part 600. The connecting piece 500 can pass through the passage 170 on the bed frame 100 to extend from the first side 150 to the second side 160 of the bed frame 100, and the matching part 600 can cooperate with the fastener 400 on the second side 160 of the bed frame 100, so that the mattress 200 can be better fitted to the bed frame 100.

[0095] Therefore, through the cooperation of the matching part 600 and the fastener 400, the connecting piece 500 and the mattress 200 are constrained, so that the mattress 200 is less likely to slip relative to the bed frame 100. Especially in the state of lifting the bed frame 100, the sliding of the mattress 200 relative to the bed frame 100 can be reduced. Further, the displacement of the mattress 200 is smaller, and the fitting degree of the mattress 200 to the bed frame 100 is higher, so that the mattress 200 is less likely to bulge out of the range of the bed frame 100, which helps to improve the user's comfort, reduce the damage of the mattress 200, and prolong the service life of the mattress 200.

[0096] In some embodiments, when the user installs, the connecting member 500 is first passed through the passage 170, and the user's hand can be located at the second side 160 of the bed frame 100, and the connecting member 500 is exerted force from the second side 160, so that the fitting part 600 can be fitted to the fastener 400, and the second side 160 can be the side of the bed frame 100 close to the ground. After the fitting is completed, the connecting member 500 abuts against the inner wall of the passage 170, so as to reduce the displacement of the mattress 200 relative to the bed frame 100. Exemplarily, the connecting member 500 has a free end, and a stretching part 510 is arranged at the free end, which is used for the user to hold for operation and stretching of the connecting member 500. Exemplarily, the connecting member 500 can also have a fixed end, which is the connecting end of the connecting member 500 and the mattress 200.

[0097] In the embodiments of the present application, the connecting member 500 extends from the first side 150 to the second side 160 of the bed frame 100 through the passage 170, so that the fitting part 600 can be fitted to the fastener 400 at the second side 160 of the bed frame 100. Please refer to Figure 8 and Figure 9 which show the schematic view of the bed frame 100 at the second side 160. If the fitting connection position of the fitting part 600 and the fastener 400 is arranged at the first side 150 of the bed frame 100, that is, the side of the bed frame 100 close to the mattress 200, the fitting connection position of the fitting part 600 and the fastener 400 is shielded by the mattress 200, so that the user is not convenient to operate the fitting connection of the two. Through the arrangement of the embodiments of the present application, the user is facilitated to operate to realize the connection and disconnection of the fitting part 600 and the fastener 400.

[0098] Here, the connecting member 500, the fastener 400 and the passage 170 are arranged correspondingly, that is, the positions and the number of the connecting member 500, the fastener 400 and the passage 170 are one-to-one corresponding. Exemplarily, please refer to Figure 3 which is provided with four passages 170, please refer to Figure 8 and in combination with Figure 9 correspondingly, four connecting members 500 are arranged, and four fasteners 400 are arranged, so that the fitting part 600 on each connecting member 500 can be fitted to the corresponding fastener 400. Of course, it can be understood that in other embodiments, the components can also be arranged one-to-one, for example, a plurality of connecting members 500 can share the same passage 170, the fitting parts 600 of a plurality of connecting members 500 can be connected to the same fastener 400, and the examples in the embodiments do not constitute improper limitation.

[0099] In addition, in some embodiments, the interval distance between the passages 170 can be set to be large, so as to better tighten the mattress 200 through the connecting member 500 and make it fit the bed frame 100. Exemplarily, in the embodiments of the present application, the interval distance between the passages 170 is greater than the length of the connecting member 500.Figure 3 In some embodiments, the two passages 170 on the second bed frame 100 are arranged at intervals, for example, near the left and right sides of the bed frame 100 respectively, and the two passages 170 on the fourth bed frame 100 are also arranged at intervals, for example, near the left and right sides of the bed frame 100 respectively.

[0100] In some embodiments, the connecting member 500 can be a woven belt or a nylon belt, etc. For example, the connecting member 500 can also be a cloth belt of other materials, etc. For another example, the connecting member 500 can also be a chain, etc. Thus, the tensile property of the connecting member 500 is good, and the connecting member 500 is not easy to deform, which helps to keep the positioning of the mattress 200 and reduce the slippage of the mattress 200 compared with the bed frame 100.

[0101] In some embodiments, please refer to Figure 3 The bed frame 100 is provided with a passage 170 near the area close to the foot and / or near the area close to the hip. For example, the second bed frame 100 and / or the fourth bed frame 100 is provided with a passage 170. The position of the mattress 200 connected with the connecting member 500 can substantially correspond to the position of the passage 170, for example, be arranged near the hip and the foot, but it can also be arranged far away from the passage 170, and the examples in the embodiments do not constitute improper limitations.

[0102] Here, the second bed frame 100 and the fourth bed frame 100 are respectively provided with a passage 170 as an example. Please refer to Figure 6 and Figure 7 which show the relative position relationship between the connecting member 500 and the passage 170, but it is only a schematic, and in practice, the connecting member 500 can be located at other positions in the passage 170.

[0103] Taking the state shown in Figure 6 as an example, no matter whether the area close to the head of the bed frame 100 is lifted or the area close to the foot of the bed frame 100 is lifted, the mattress 200 at the hip position is subjected to the force F1 with upward component and exists upward displacement. Here, the connecting member 500 can effectively pull the mattress 200 at the hip position to prevent the upward displacement of the mattress 200, thereby improving the fit of the mattress 200 with the bed frame 100. Taking Figure 7 as an example, when the bed frame 100 is lifted, the mattress 200 at the foot position is often subjected to the force F2 with backward and upward components and exists backward and upward displacement. When the connecting member 500 is connected to the bed frame 100, since the connecting member 500 has small deformation and good tensile resistance, the connecting member 500 can effectively prevent the backward and upward displacement of the mattress 200, which helps to improve the fit of the mattress 200 with the bed frame 100.

[0104] In some embodiments, please refer to Figure 10The one end of the connecting piece 500 is directly connected to the mattress 200. In other embodiments, please refer to Figure 11 The reinforcing part 210 is arranged on the mattress 200. Exemplarily, four reinforcing parts 210 are arranged, which are arranged one by one with the four connecting pieces 500, that is, each connecting piece 500 is connected to a corresponding reinforcing part 210 (see the schematic diagram of the cooperation between the connecting piece 500 and the reinforcing part 210 in Figure 12 ). Of course, it can be understood that the number of the reinforcing part 210 is not limited to the above, and generally, the number of the reinforcing part 210 can be matched with the number of the connecting piece 500.

[0105] Here, please further refer to Figure 12 The reinforcing part 210 has a connecting surface 211, and the connecting piece 500 is connected to the connecting surface 211. Thus, the connecting piece 500 and the mattress 200 are not in point contact but in surface contact, which helps to strengthen the strength of the connecting position of the two, so that the connecting piece 500 drives a larger area of the surface of the mattress 200 to move when working, rather than driving a smaller area (for example, an approximately linear area on the mattress 200) of the mattress 200 to move, thereby reducing the deformation amount of the mattress 200 when the connecting piece 500 restricts the mattress 200. Exemplarily, the reinforcing part 210 can be substantially plate-shaped.

[0106] In some embodiments, please refer to Figure 13 The cooperation part 600 includes a first sub-part 610 and a second sub-part 620, and the connecting piece 500 is clamped between the first sub-part 610 and the second sub-part 620. Exemplarily, the first sub-part 610 and the second sub-part 620 can form a detachable cooperation connection, for example, the first sub-part 610 and the second sub-part 620 are detachably connected through magnetism, or the first sub-part 610 and the second sub-part 620 are threadedly connected, for example, the first sub-part 610 and the second sub-part 620 are clamped or connected through a rivet, for example, the first sub-part 610 and the second sub-part 620 are connected through threads or other ways while the first sub-part 610 and the second sub-part 620 are also magnetically adsorbed. Of course, in other embodiments, the first sub-part 610 and the second sub-part 620 can also be other ways of detachable connection or non-detachable connection, for example, the first sub-part 610 and the second sub-part 620 can be connected through welding, and the examples in the embodiments do not constitute improper limitations.

[0107] In some embodiments, the cooperation part 600 and the fastener 400 are detachably connected through magnetism. That is, the cooperation part 600 and the fastener 400 both have magnetism, and they can be magnetically adsorbed to each other to form a detachable connection.

[0108] Exemplarily, on the basis that the fitting part 600 and the fastener 400 form detachable connection through magnetism, please refer to Figure 14 , the fastener 400 has a protruding part 410, such as a protruding column or the like. In addition, exemplarily, the fastener 400 can also be provided with a connecting hole 420, which is used for connecting the fastener 400 to the second side 160 of the bed frame 100 through a screw, of course, the connecting mode of the fastener 400 and the bed frame 100 is not limited to the above in other embodiments.

[0109] Corresponding to the protruding part 410, please refer to Figure 15 , the fitting part 600 is provided with a recessed part 630, such as a through hole or a groove or the like, when the fitting part 600 includes the first sub part 610 and the second sub part 620, generally, the first sub part 610 and the second sub part 620 are both provided with the recessed part 630 correspondingly, for example, both the first sub part 610 and the second sub part 620 are provided with a through hole as the recessed part 630 correspondingly, and the through holes of the two are continuous with each other.

[0110] In the state that the fitting part 600 cooperates with the fastener 400, at least a part of the protruding part 410 is fitted in the recessed part 630. Exemplarily, as shown in Figure 16 , the protruding part 410 passes through the recessed part 630. Further as shown in Figure 17 , which shows a schematic view of the fitting part 600 cooperating with the fastener 400 and fixing the connecting piece 500, in order to avoid the protruding part 410, the connecting piece 500 can be provided with an avoiding hole correspondingly to the protruding part 410, of course, it can also not be provided, the example in the embodiment does not constitute improper limitation thereto.

[0111] It can be understood that in other embodiments, the protruding part 410 can also be provided on the fitting part 600, and the recessed part 630 can also be provided on the fastener 400, the example in the embodiment does not constitute improper limitation thereto.

[0112] In some embodiments, on the basis that the detachable connection between the fitting part 600 and the fastener 400 is formed through magnetism, the magnetization direction of the fitting part 600 is perpendicular to the surface of the bed frame 100. Generally, the bed frame 100 is placed on the horizontal ground, and the magnetization direction of the fitting part 600 is also perpendicular to the horizontal direction, for example, it is generally a vertical direction.

[0113] Here, the magnetization direction of the magnet at the fitting part 600 is the direction perpendicular to the surface of the side of the bed frame 100 close to the ground, that is, there is only one kind of magnetic pole on the plane of the bed frame 100, and the fitting part 600 can be automatically centered and positioned on the fastener 400 during installation, and the installation difficulty is facilitated compared with other direction magnetization magnets.

[0114] Exemplarily, if the fitting part 600 adopts a structure including a first sub-part 610 and a second sub-part 620, the first sub-part 610 can be arranged as the N pole of the fitting part 600, and the second sub-part 620 can be arranged as the S pole of the fitting part 600, or vice versa.

[0115] In a further example, on the basis of adopting the magnetic adsorption scheme, the protruding part 410 and the recessed part 630 are also arranged, at this time, the magnetization direction of the fitting part 600 is the axial direction of the protruding part 410 and / or the recessed part 630.

[0116] It can be seen that when the connection mode between the fitting part 600 and the fastener 400 is arranged as a magnetic attraction structure, the structure is simple to install, and the self-positioning function can be realized through the arrangement of the magnetic pole position, so that the user can conveniently realize the accurate cooperation between the fitting part 600 and the fastener 400.

[0117] However, since the fitting part 600 and the fastener 400 adopt a magnetic attraction mode, an interference magnetic field will be formed, which may interfere with medical equipment when applied in the medical field. For example, when the electric bed with this structure is used as a hospital bed, this situation may occur.

[0118] Therefore, in some embodiments of the present application, the fitting part 600 and the fastener 400 are connected in a non-magnetic attraction mode. Correspondingly, the connection mode between the fitting part 600 and the connecting part 500 can also adopt a non-magnetic attraction mode.

[0119] For example, in some embodiments, referring to Figure 18 , the fastener 400 is provided with a protruding part 410, and the protruding part 410 is provided with at least one protrusion 411 protruding radially from the protruding part 410 along the radial direction of the protruding part 410. Correspondingly, referring to Figure 19 , the fitting part 600 is provided with a recessed part 630, and the recessed part 630 includes a through hole. The cross section of the through hole in the recessed part 630 is adapted to the cross section of the protruding part 410 at the position of the protrusion 411, and at least a part of the protruding part 410 and the protrusion 411 can pass through the through hole.

[0120] Exemplarily, referring to Figure 20When the fitting portion 600 is fitted with the fastener 400, after the protruding portion 410 passes through the through hole of the recessed portion 630 and rotates relative to the recessed portion 630, the protrusion 411 is out of the range of the recessed portion 630, and then the protrusion 411 abuts against the side of the fitting portion 600 away from the bed frame 100, thereby achieving the fitting connection between the fastener 400 and the fitting portion 600. When disassembly is needed, the fitting portion 600 and the recessed portion 630 are rotated again relative to the protruding portion 410, and the protrusion 411 is again within the range of the recessed portion 630, and then the protruding portion 410 and the protrusion 411 can pass through the recessed portion 630, thereby disengaging the protruding portion 410 from the recessed portion 630.

[0121] Here, the number of protrusions 411 can be set to N, N being a natural number approximately equal to 1, and the protrusion 411 on the protruding portion 410 passes through the through hole of the recessed portion 630, and after rotating 180 / N°, the protruding portion 410 and the recessed portion 630 can achieve a fitting connection. Exemplarily, in Figures 18 to 20 , the number of protrusions 411 is set to 3, that is, N is 3, and the three protrusions 411 are uniformly arranged along the circumference. Of course, in other embodiments, the number of N can be different from the example in the figure.

[0122] Exemplarily, referring to Figure 22 , the recessed portion 630 is provided with a flange portion 631 extending to the radially inner side of the through hole, and the side of the flange portion 631 away from the protruding portion 410 has a flange face 632. Please refer to Figures 22-24 , and refer to Figure 22 and Figure 24 , the flange face 632 is arranged obliquely. Here, refer to Figure 22 , the flange portion 631 is provided with two mutually symmetrical flange portions corresponding to the two protrusions 411 of the protruding portion 410. In other embodiments, when the number of protrusions 411 is different, the number of flange portions 631 is also correspondingly different. When the protruding portion 410 is arranged on the fastener 400, the side of the flange portion 631 away from the protruding portion 410 is the side away from the fastener 400, which is usually the side away from the bed frame 100.

[0123] In addition, referring to Figure 23 , in some examples, a stop portion 633 can also be arranged at the flange face 632, and the stop portion 633 is located at the end position of the movement path of the protrusion 411 on the flange face 632, so as to limit the protrusion 411 and reduce the situation that the protrusion 411 is out of the flange face 632 due to excessive rotation by the user. Assuming that the direction outward from the paper in Figure 23 is the height direction, the flange face 632 gradually increases in the height direction along the movement path of the protrusion 411 to form an inclined shape, and the stop portion 633 can be located at the end of the higher side of the flange face 632.

[0124] After the protruding portion 410 is inserted into the through hole, the protrusion 411 is moved to the side of the flange portion 631 with the inclined flange surface 632, and then the protruding portion 410 is rotated so that the protrusion 411 is rotated along the flange surface 632. Since the flange surface 632 is inclined, as the protrusion 411 is rotated, the mutual approach between the protrusion 411 and the flange surface 632 gradually increases, and the rotating torsion force gradually increases, and the fastener 400 and the cooperating portion 600 are tightly and cooperatively fastened. Please refer to Figure 25 which shows a schematic view of the state that the cooperating portion 600 and the fastener 400 are cooperatively fastened and the connecting member 500 is fixed.

[0125] It can be understood that in the above embodiment in which the flange surface 632 is arranged, the axial length of the protruding portion 410 only needs to satisfy that after it is cooperated with the recessed portion 630, the protrusion 411 can be cooperated with the flange surface 632, and the flange portion 631 and the flange surface 632 are located in the through hole of the recessed portion 630, so that the axial length of the protruding portion 410 can be arranged to be shorter.

[0126] Please refer to Figure 26 After the installation is completed, the length of the connecting member 500 required is L1, but in order to cooperatively fasten the cooperating portion 600 on the connecting member 500 to the fastening portion, an acting force needs to be applied to the connecting member 500 in a direction away from the mattress 200, and thus the length of the connecting member 500 required during the installation is L2, and L2 is longer than L1. In order to be able to realize the installation, the length of the connecting member 500 needs to be arranged as L2, which leads to that the actual length is longer than the length L1 required after the installation, and thus the mattress 200 has a certain movable space. The smaller the difference between L2 and L1 is, the smaller the sliding space of the mattress 200 is, and the length of L2 is related to the length L3 of the protruding portion 410, and the smaller the length L3 of the protruding portion 410 is, the smaller L2 can be. The embodiments of the present application can shorten the axial length of the protruding portion 410, i.e. the length of L3, and thus can reduce L2 to reduce the displacement amount of the mattress 200.

[0127] It can be understood that in the above embodiments, the protruding portion 410 is arranged on the fastener 400, and the recessed portion 630 corresponding to the protruding portion 410 is arranged on the cooperating portion 600, which is taken as an example for description. However, in other embodiments, the protruding portion 410 can be arranged on the cooperating portion 600, and the recessed portion 630 can be arranged on the fastener 400, and the examples in the embodiments do not constitute improper limitation thereto.

[0128] In some embodiments, please refer to Figure 27The additional member 700 can be arranged to connect the fitting part 600 and the fastener 400. For example, the additional member 700 is arranged to connect the fastener 400 and clamps the fitting part 600 between the additional member 700 and the fastener 400. The connection between the additional member 700 and the fastener 400 can be a threaded connection, a clamping connection, a magnetic connection, etc. The examples in the embodiments do not constitute improper limitations. For example, the additional member 700 is provided with a first threaded section 710, the fitting part 600 is provided with a fitting hole 640 as an avoidance, and the fastener 400 is provided with a second threaded section 430. The additional member 700 and the fastener 400 can be engaged with each other through the first threaded section 710 and the second threaded section 430, thereby achieving a connection. The first threaded section 710 can be an external thread, and the second threaded section 430 can be an internal thread. If the connector 500 hinders the connection between the additional member 700 and the fastener 400, an avoidance hole or the like can be arranged on the connector 500, such as the aforementioned fitting hole 640, which is easily understood by those skilled in the art.

[0129] In some further examples, please refer to Figure 28 The first threaded section 710 can be provided with an extension section 720 on the outside. The inside of the first threaded section 710 can have a section without a thread, such as a portion passing through the fitting hole 640 of the fitting part 600 without a thread, or the inside of the extension section 720 can be entirely the first threaded section 710. The examples in the embodiments do not constitute improper limitations. Figure 29 The extension section 440 is provided with an extension space 441 inside, which is continuous with the aforementioned second threaded section 430, for accommodating the extension section 720.

[0130] In use, when the assembly is completed, the first threaded section 710 of the additional member 700 is engaged with the second threaded section 430 of the fastener 400, and at the same time, the extension section 720 is accommodated in the extension space 441. For example, the inner wall of the extension section 440 wraps at least a portion of the extension section 720. Generally, the extension section 720 does not protrude from the extension space 441 to avoid forming a protruding structure, but the examples in the embodiments do not constitute improper limitations.

[0131] Here, the matching length of the first threaded section 710 and the second threaded section 430 will affect the connection strength, but if the matching length of the first threaded section 710 and the second threaded section 430 is too long, the user needs to turn more turns when using, thereby increasing the installation time. In some embodiments of the present application, the extension section 720 is provided, and the connection strength is increased through the cooperation of the extension section 720 and the extension section 440, and then the matching length of the first threaded section 710 and the second threaded section 430 can be set smaller to reduce the installation time.

[0132] In addition, it can be understood that the additional part 700 and the matching part 600 shown in the drawings of the present application are two separate components, and in other embodiments, the additional part 700 and the matching part 600 can also be a one-piece component, that is, the additional part 700 can be a part of the matching part 600, and then the above-mentioned embodiments can also be understood as the threaded connection between the fastener 400 and the matching part 600. In addition, in other embodiments, an external thread can also be provided on the protruding part 410 in any of the foregoing embodiments, and an internal thread can also be provided on the recessed part 630, and the protruding part 410 and the recessed part 630 can be engaged with each other through the external thread and the internal thread, thereby achieving the matching connection.

[0133] For example, please refer to Figure 30 The fastener 400 can also be provided with the protruding part 410, and the protruding part 410 can be provided with an external thread as the second threaded section 430 described above, and the additional part 700 can be provided with an internal thread as the first threaded section 710 described above, and the two can be connected through threaded cooperation. For example Figure 31 As shown, the protruding part 410 can also be provided with an internal thread, and the additional part 700 can also be provided with an external thread in correspondence, and the two can be connected with each other.

[0134] In these embodiments, since the magnetic attraction cooperation mode is not adopted, no magnetic field is generated in each component, which will not interfere with the operation of the medical equipment, and can be applied to the medical field. In addition, the installation and disassembly between the fastener 400 and the matching part 600 in these embodiments are relatively simple, and are convenient for the user to operate.

[0135] In some embodiments, the embodiments of the present application provide a buckle structure to realize the cooperation of the matching part 600 and the fastener 400.

[0136] Please refer to Figure 32The fastener 400 further comprises a third side 470, and a limiting part 450 is arranged on the third side 470 of the fastener 400. The limiting part 450 is provided with a limiting slot 451, which is used to cooperate with the matching part 600 to prevent the matching part 600 from being pulled out. Exemplarily, two limiting parts 450 can be arranged at intervals, and a space for the connecting piece 500 to pass through is formed between the two limiting parts 450. Of course, in some embodiments, the limiting part 450 can not be arranged or other numbers of limiting parts 450 can be arranged, and the examples in the embodiments do not constitute improper limitations.

[0137] Please refer to Figure 33 The fastener 400 further comprises a fourth side 480, and the third side 470 and the fourth side 480 can be opposite sides, for example, the upper side and the lower side. A fastening slot 460 is arranged on the fourth side 480 of the fastener 400. The fastening slot 460 comprises a first slot 461, a second slot 462 and a third slot 463 arranged in sequence, and the entrance of the fastening slot 460 is located on the side of the first slot 461 away from the third slot 463. The width of the fastening slot 460 gradually increases from the first slot 461, the second slot 462 to the third slot 463. Exemplarily, the first slot 461 has a first width, the second slot 462 has a second width, and the third slot 463 has a third width, and the first width < the second width < the third width.

[0138] Here, in order to realize the cooperative connection between the fastener 400 and the matching part 600, please combine Figure 32 and Figure 33 with Figure 34 In the embodiments of the present application, a locking piece 800 is further arranged. The locking piece 800 comprises a first rod piece 810 and a second rod piece 820 arranged at intervals, and the first rod piece 810 and the second rod piece 820 have a first interval. The first rod piece 810 and the second rod piece 820 are provided with a first check end 811 and a second check end 821 respectively and outwardly extended on the side away from each other. The first check end 811 and the second check end 821 have a second interval, and the second interval is greater than the first interval. Moreover, the second width is less than the second interval, and the third width is greater than the second interval. The first check end 811 and the second check end 821 can be arranged obliquely to the first rod piece 810 and the second rod piece 820. In addition, the ends on the other side of the first rod piece 810 and the second rod piece 820 can be connected to each other to form a stop matching part 830.

[0139] In use, please refer to Figure 35 The matching part 600 can be clamped into the limiting slot 451 of the limiting part 450 on the third side 470 of the fastener 400.

[0140] Please combine Figure 33 and Figure 34, the first check end 811 and the second check end 821 of the locking piece 800 firstly enter the first slot 461 from the entrance of the fastening groove 460, at this time, the first check end 811 and the second check end 821 are in contact with the inner wall of the first slot 461, and due to the limitation of the inner wall of the first slot 461, the second distance between the first check end 811 and the second check end 821 will be smaller than that in the state without external force.

[0141] Please refer to Figure 36 , with the movement of the locking piece 800, the first check end 811 and the second check end 821 enter the second slot 462, the first check end 811 and the second check end 821 are no longer restricted by the inner wall of the first slot 461, but are restricted by the inner wall of the second slot 462, and since the second width of the second slot 462 is greater than the first width of the first slot 461, the second distance between the first check end 811 and the second check end 821 can be correspondingly increased, at this time, the first check end 811 and the second check end 821 are more difficult to retreat back to the first slot 461, thereby forming the cooperation between the locking piece 800 and the fastener 400.

[0142] Please refer to Figure 37 , with the movement of the locking piece 800, the first check end 811 and the second check end 821 enter the third slot 463, at this time, the first check end 811 and the second check end 821 are completely unfolded, and exemplarily, when unfolded, will move along the step surface formed at the joint of the second slot 462 and the third slot 463 and collide with the inner wall of the third slot 463, thereby possibly generating a slight sound, which can be used as a prompt sound to prompt the user that it has been installed in place. At this time, please refer to Figure 38 , the stop cooperation part 830 formed by the mutual connection of the first rod 810 and the second rod 820 is located at the position abutting against the surface of the third side 470 of the fastener 400, so as to reduce the possibility of falling off of the locking piece 800. Thus, the locking cooperation is completed.

[0143] When it is needed to release the cooperation connection, the user can pull the locking piece 800 to the position of the second slot 462 under the application of a little pulling force, so that the cooperation part 600 can be separated from the locking piece.

[0144] The buckle cooperation structure does not form an additional magnetic field, does not interfere with medical equipment, and is relatively simple to install and disassemble.

[0145] It can be seen that in the embodiments of the present application, the cooperation connection between the cooperation part 600 and the fastener 400 is easy to be implemented and released, and the operation of the user is very convenient.

[0146] Correspondingly, please refer to Figures 1 to 38The embodiments of the present application also provide a support cushion positioning structure for positioning a first component relative to a second component, one of the first component and the second component being a support cushion and the other being a support frame. Exemplarily, the support cushion can be the aforementioned mattress 200, and the support frame can be the aforementioned bed frame 100; or, the support cushion can be a seat cushion, and the support frame can be a recliner chair, etc. It can be understood that the support cushion positioning structure is more suitable for a support frame that is capable of changing state by mechanical driving, and is also suitable for a support frame that is capable of changing state by manual driving. Of course, the examples in the embodiments of the present application do not constitute undue limitations thereto.

[0148] Here, the connecting piece 500 can pass through the passage 170 so that the cooperating part 600 cooperates with the fastener 400.

[0149] The specific structure, arrangement position and cooperation relationship of the cooperating part 600, the fastener 400 and other components, etc. will be described in the aforementioned embodiments, and thus will not be described herein again to avoid excessive length of the present application.

[0150] Correspondingly, the embodiments of the present application also provide a use method of the electric bed, comprising the following steps:

[0152] S200. making the connecting piece 500 on the mattress 200 pass through the passage 170 on the bed frame 100 so that the cooperating part 600 on the connecting piece 500 cooperates with the fastener 400 on the second side 160 of the bed frame 100, thereby relatively fixing the bed frame 100 and the mattress 200.

[0153] The relative position and connection relationship of the connecting piece 500, the passage 170, the cooperating part 600 and the fastener 400, and the assembly method can be referred to the aforementioned embodiments, which are the same as the descriptions in the aforementioned structural embodiments, and thus will not be described herein again to avoid excessive length of the present application.

In other words, only one magnetic pole exists on the same plane. During installation, the axially magnetized magnet can be automatically centered and positioned, making the installation between the mating part 600 and the fastener 400 very convenient.
